MC78M00/D

MC78M00, MC78M00A,

NCV78M00 Series

500 mA Positive Voltage

Regulators

The MC78M00/MC78M00A Series positive voltage regulators are

identical to the popular MC7800 Series devices, except that they are

specified for only half the output current. Like the MC7800 devices,

the MC78M00 three-terminal regulators are intended for local,

on-card voltage regulation.

Internal current limiting, thermal shutdown circuitry and safe-area

compensation for the internal pass transistor combine to make these

devices remarkably rugged under most operating conditions.

Maximum output current, with adequate heatsinking is 500 mA.

Features

•No External Components Required

•Internal Thermal Overload Protection

•Internal Short Circuit Current Limiting

•Output Transistor Safe-Area Compensation

•MC78M00A High Accuracy (±2%)

Available for 5.0 V, 8.0 V, 12 V and 15 V

•Pb-Free Packages are Available*

•NCV Prefix for Automotive and Other Applications Requiring Site

MC78M00, MC78M00A, NCV78M00 Series DEFINITIONS Line Regulation - The change in output voltage for a change in the input voltage. The measurement is made under conditions of low dissipation or by using pulse techniques such that the average chip temperature is not significantly affected. Input Bias Current - That part of the input current that is not delivered to the load.

MC78M00, MC78M00A, NCV78M00 Series APPLICATIONS INFORMATION Design Considerations regulator is connected to the power supply filter with long wire lengths, or if the output load capacitance is large. An input bypass capacitor should be selected to provide good high frequency characteristics to insure stable operation under all load conditions. A 0.33 mF or larger tantalum, mylar, or other capacitor having low internal impedance at high frequencies should be chosen.
